| **A car with a mass of 1500 kg moves with equal slowness with an acceleration a = 20 m / s2. Determine the strength of its inhibition.**

Solution of the problem, according to Newton’s second law.

Let’s write the formula: F = m * a.

Let’s see what is given to us in the tasks:

m – weight (1500 kg);

a – acceleration (20 m / s²);

Substitute in the formula and solve:

F = 1500 * 20;

F = 30,000 H;

Conversion to other units of measurement:

F = 30 kN.

Answer: F = 30 kN.
